Non reportable claim injury..

I was recently in a car accident. We were waiting for a car to make a left turn and we were hit from behind. The impact caused me to be thrown forward. My seat belt did not catch me immediately so I was thrown pretty hard and almost hit the dash. There was no air bags. I started hyperventilating. I had an anxiety attack and it was still going on when the paramedics got their. I opted to ride to the hospital in the ambulance because my lower back was hurting. I was diagnosed with fibromyalgia in 1998 but I have been in remission for several years and on no prescription medicines any more. My pain has been minimal until the accident. My back has been hurting for days and I cannot stand for long periods or sit for too long. The police put it down as a non re portable accident. Will this hinder me getting any help with medical bills? Also how do things like this work when the person hit has had a history of Fibromyalgia? I am really concerned. I want to go to the chiropractor because I do not want this pain to become debilitating. The police officer never spoke to me or asked me any questions and I was the passenger in the front seat. My daughter was in the back and two little children. One of the children has been complaining of his neck and back hurting and the driver hurt her leg. She was watching the lady hit us so she consciously kept her foot on the brake so as not to hit any other cars.
